Specification of Letters Patent.

Patented July 2, 1918 Application filed May 16, 1917. Serial No.169,012.

To all whom it may concern:

Be it known that I, L. C. LAURENT, a citizen of the United States,residing at Denver, in the county of Denver and State of Colorado, haveinvented new and useful Improvements in Temporary Binders, of which thefollowing is a specification.

This invention relates to paper files and binders, and more especiallyto pins and covers; and the object of the same is to produce a temporarybinder in which books, pamphlets, and loose leaves can be bound andretained and from whose pins they can be removed when desired.

The invention consists particularly in the specific means for fasteningthe free ends of the covers to each other so as to prevent racking whichso often tears these covers from the back of the binding and renders thedevices unfit for further use.

Details of the invention will be set forth in the followingspecification, reference be ing had to the accompanying drawings whereinFigure 1 is a perspective view of this device open, ready for theinsertion of leaves, showing a few leaves already in place on the pins.

2 is a perspective view of this device about to be closed, partly brokenaway on one of the strips to show the sockets.

Fig. 3 is a sectional detail on the line 3-3 of Fig. 1.

The leaves are lettered L herein, and this letter may be taken toinclude pamphlets, books, or other similar articles which are boundwithin this device. For binding them therein, the pins P are provided,their free ends being removably inserted under hookshaped guards G asshown.

Coming now to the present invention, the numeral 1 designates the backof the binding which may well be of wood having holes formed edgewisethrough it as seen in Fig. 3, and into opposite ends of these holes Iinsert the shanks of the pins P and guards G. The shank 12 of the pin isdriven into the board until the angle in the pin comes up against theedge of said board. The shank 13 of the guard is also driven into theboard, but the inner extremities of the shanks do not meet within thehole. In that edge of the board next the upright portion of the guard iscut a notch 14, so that the guard may be turned down to one side topermit the passage of the leaves over the point of the pin. P. Overlyingthe upright portions of the elements or strips 2 of flexible material,preferably tacked to the edges of the wooden back 1, and connected withthese strips in turn are the boards 3 and 1 which constitute the coversof the binder. At the outer or free edge of each board is a strippreferably of wood, and these strips are numbered 5 and 6 respectively,their aggregated width being equal to that of the backboard 1, so thatwhen their free edges are closed together the covers 3 and 4: will standparallel and the entire structure will be boxshaped so as to carefullyand thoroughly protect the contents.

As seen in Fig. 2, a fastening device is provided on the front faces ofthe strips 5 and 6, the same being herein illustrated as a hook 7pivoted to the strip 5 and engaging a headed pin 8 in the strip 6, butany suit able fastening device may be used. The essence of the inventionconsists in providing one of the strips, as 6, with a pair of holes orsockets 9 in its edge, and the other strip as 5, with a pair of pins ordowels 10 projecting from its edge and accurately disposed so as toenter the holes or sockets when the two strips are brought together.Thereafter the fastening device is actuated to lock the strips in thiscondition, and the binder is laid away.

When now it is desired to gain access to th binder, as for inspectingpapers already on file, removing some of them, or inserting new ones,the complete device is taken from the shelf or other point of storage,the fas toning device disconnected, and the two strips 5 and 6 spreadapart so that the entire binder can be laid out flat on the desk as seenin Fig. 1. In so doing the flexible or binding strips 2 connecting thecovers 3 and 4 with the backboard 1 will fold or bend like hinges. Afterthe use of the device the parts are restored to their original position,and the pins 10 enter the socket 9. Now it will be seen that, eventhough the fastening device should become unfastened, it is impossiblefor the strips 5 and 6 to move longitudinally and relatively to eachother, and therefore racking of the boards 3 and 4 which will causeinjury to and finally destruction of the fabric strips 2 is avoided. Thestrips 5 and 6 are preferably of Wood so as to protect the front edgesof the leaves or matter bound on the pins, the same as does the backboard 1, and the covers or boards 22 and 4 may be of any suitablematerial. The size of parts is of course immaterial.

hatis claimed as new is A temporary binder comprising a backboard formedwith openings in its opposing edges, a series of holding memberscomprising independent pins and guards therefor, each pin and guardhaving a shank adapted to be inserted in one of said openings, the 10backboard adjacent the guards being formed with notches to permit theguards to be swung laterally from the pins, cover boards connected Withthe respective edges of the backboard, and means for connecting the 15LOUIS o.
